For the last few years, the Humble Bundle has been supporting both charities and independent game developers by offering a "pay what you want" deal for a collection of games, with the customers deciding which of their dollars go to charity and which go to the developers.
This year's bundle offers Rochard, Shatter, S.P.A.Z., Torchlight, and Vessel. Keeping in line with past bundles, Humble Indie Bundle 6 incentives you to donate more by offering Dustforce those that pay more than the average donated.
For many, this is a chance for gamers to offer support of both game developers and charities. For others, it's an excuse to finally check out some games many haven't gotten around to. Either way, everybody wins.
